Specification of Letters Patent.

Application tiled August 31, 1912. Serial No. 718.028.

To all whom t may coiwem Be it known that we. BRUN() F. GOETH- xizn and HUGH Rooney, citizens of the lnitedl States, and residents of Hartford and Statefof Connecticut, and whose postoliice addressesare Hartford. Connecticut.`

dnoe an improved couplingto connect to-.

gether the abutting ends of piping. and it is particularly adapted for use in electrical work to c'onnect together the ends of what is known as rigid iron conduit.

More especially we provide u device by means of which pipe or conduit provided with right-hand threads can be secured tol. ether and drawn up into proper position. Generally speaking this is accomplished by providing a coupling, one member of which can be held o einst rotation'while :t pipe is being screwe into it and then is released so that it will tnrn 'freely in the coupling while the other pipe is being screwed in.

An embodiment of the invention is shown in the drawings: Figure l shows a central vertical section of a device made in accord` ance with our invention. Fig. 2 is' a per spective view of the split ring, and Fig. 3 is a sectional end view on the line 3-3 of Fig. 1.

.a denote the pipes which are to be joined together each of which is lprovided at its end with a right-hand threa 40 10 denotes in general the coupling comprising the sleeve 11, one end of which is threaded to tit the pipe n; the other-end being recessed as at 1Q. ln this recess is located a ring 13 longitudinally slotted as at.

14. The spring of the nietal is sach as to allow of its being compressed to pass through the ripening l5 in the end of the sleeve to position it within the recess. the shoulder 16 preventing its accidental remoral. The length of this sleeve with respect to the length of ie recess is snch that the former can move'.l ongitndinally in the recess. f

l 17 is a pin mounted in the sleeie and projecting into the recess and o f such a size that it will fit in the slot 14 of the ring 13 and constitute adriving connection between the sleeve. 11 and the ring 13, and b means of which a pipe may be threaded into the ring, or the ring threaded onto a pipe.

lf now the ring is moved to theextreme left-hand position so that the pin 17 lies in the slot, the ring is held against rotation and the pipe b can be readily screwed into it. The sleeve and the ring can'now be moved relatively to one another to disengage the ring from the pin, and then the pipe a can be screwed into the sleeve 1l or the sleeve l1 can be turned to draw into it the pipe o; during this operation the sleeve is free to turn with respect to the ring 13 thus preventirbig the ring from screwing oil' of the pi e he convenience of nsin pi Jing or conduit provided with rightan threads at each end will be readily apparent and there are many cases when this sim le coupling can be utilized where it is di cult if not impossible to use the ordinary union with right and left-hund threads.

@It is probable that the invention is susceptible of modifcation'and alterations and it is our intention tojinclude in the `apl pended claims any and all such changes of construction which come fairly within the scope oi the invention.

iVe claim as our invention:

1. A coupling comprising a sleeve threaded at one end, an internally threaded member located within said sleeve near one end thereof and adapted for relative movement with respect thereto, and a discngageable 'driving connection between said sleeve and member.

2. ln a device of the character specified o sleeve threaded at` one end, an internally threadedi member located therein und movable rotaiily with respect thereto, and a disengagcable driving connection between said sleeve and member.

3. ln a device of the character described :l sleeve h-.Lving a thread at one end for engagement with a pipe and a recess at the other end, a member located within said recess and adapted for longitudinal and rotary movement with respect thereto, a thread on said member adaptedfor engagenient with thepipe. and a disengageable driving connection between said sleeve and member.

4. In a coupling device a sleeve having a.

l.ngitudinal bore, a thread cut into the bore oi nid sleeve at one end and adapted to en-Y gage an end of the pipe, a recess in the other' end of the sleeve provided With a shoulder at its outer end, a split ring located within said recess and adapted for longitudinal nml rotary movement relative to the sleeve. said ring being interiorly threaded to receive the vnd of a pipe an means for temporarily holding said ring gainst relative rotary motion.

5. A coupling device comprising a sleeve threaded at one end to receive the end of a pipe and recessed at its opposite end; a s lit ring located in the recess and movable on-l gitndinally of the sleeve, means for limting the extent of longitudinal movement. of the ring, a pin mounted in the sleeve and projecting into saidrecess and adapted to engage said ring in ,one of its extra positions to hold it against rotation, said rin being threaded to engage the threaded en of a pipe, the threads in said sleeve and ring being both cnt in the saine direction.

A coupling com rising a sleeve provided at one end withD threaded means for attachment to a pipe, a member located within the opposite end of said sleeve and adapted for relative rotary and longitudinal movement therein, said member being provided with means for engagement with a pipe, and a discngageable driving connection between said sleeve and member.

T. The herein described art1cle of manu- -ed for attachment t0 a pipe, said member being normally movable relative to said sleeve, and 'a driving connection between said sleeve and.mcmber operative while the latter is being en aged with a pipe.

9. The herein escribed article of manufacture which is a complete couplingi'l'or pipes, conduits, etc, comprising a siieve threaded at one end for engagement with a pipe, and recessed in its opposite end, a ring located and confined within said recess and threaded to engage the end of a pipe, means on said sleeve engageable with said ring to revent its rotation relative to said sleeve W ile it is being threaded onto a pipe, said ring being disengageable from said means to permit of its rotation relative to said sleeve while the latter is being threaded onto a pipe.
